摘　　要：通过对水晶屯金矿床与区域上典型金矿床的硫、铅、氢、氧等稳定同位素的对比研究，阐明本区金矿成矿物质主要来源于太古宇崇礼杂岩，太古宙区域变质作用仅形成金的初步富集，印支—燕山早期的构造岩浆活动促成石英脉主体形成，燕山期继承性构造岩浆活动对先成脉体的叠加改造作用是成矿的重要因素，成矿流体来源于岩浆水．本矿床为具有层控性质的岩浆热液型矿床．By comparing Shuijingtun gold deposit with typical gold deposits in the same region on S Pb H O isotopic geochemistry,the authors conclude that metallogenetic material was derived mainly from Shuijingtun structural stratigraphic unit Archeozoic regional metamophism only resulted in initial enrichment of gold. Structural magmatic activity in Indo Chinese early Yanshan epoch helped to bring about the main body of quartz veins The inherited structural magmatic activity in Yanshan epoch was the main factor of gold mineralization Mineralizing fluid was mainly originated from magmatic water It's defined that Shuijingtun gold deposit is of stratabound magmatic hydrothermal type Its metallogenic modle is established
